Abstract

Dispositif de réfrigération et de congélation, comprenant un tiroir de stockage (100), un ensemble électrolytique de désoxygénation (200), un dispositif de détection tactile (500) et une soupape d'air électrique (300). L'ensemble électrolytique de désoxygénation (200) est utilisé pour consommer de l'oxygène dans un espace de stockage de telle sorte qu'un air pauvre en oxygène et riche en azote soit obtenu dans l'espace de façon à établir une atmosphère gazeuse pour la conservation d'aliments. L'intensité de la respiration aérobie des aliments, en particulier des fruits et des légumes, est réduite grâce à la diminution de la teneur en oxygène dans l'espace de stockage, assurant simultanément une action respiratoire de base et empêchant la respiration anaérobie des aliments, ce qui permet d'atteindre le but de conservation à long terme des aliments. Lorsque le dispositif de détection tactile (500) détecte qu'un utilisateur est sur le point d'ouvrir le tiroir de stockage (100), la soupape d'air électrique (300) ouvre un trou traversant sur le tiroir (100) de sorte que l'intérieur et l'extérieur de l'espace de stockage communiquent, la différence de pression entre l'intérieur et l'extérieur du tiroir étant éliminée, et ainsi le problème selon lequel un tiroir est difficile à ouvrir en raison du montage de l'ensemble électrolytique de désoxygénation (200) est résolu; un utilisateur peut ouvrir le tiroir de stockage (100) avec moins d'effort, et l'expérience d'utilisation de l'utilisateur est ainsi améliorée.
